JForum - http://www.jforum.net[LINQ in Action] Connection error when running HelloLinqToSql System.Data.SqlClient.SqlException was unhandled
Message="A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"

I'm pretty sure that means it can't open the database however I'm not sure what exactly I've done wrong. Any suggestions to get me jump started here?

This is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Data.Linq;
using System.Data.Linq.Mapping;
using System.Text;
